Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/09/2010 [ Schema ]

CS Extension

Note 1: When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension detail are available, record the code with extension detail in preference to a statement of FIGO stage. FIGO Stage III is assigned based on tumor extension and/or regional lymph node involvement. Code CS Extension based on a physician's statement of FIGO Stage III only if it is known that the stage value is assigned because of tumor extension.
Note 2: FIGO no longer includes Stage 0 (Tis) for this site.
Note 3: According to AJCC, pelvic wall is defined as muscle, fascia, neurovascular structures, or skeletal portions of the bony pelvis.
